20190004405
The present invention relates to the field of handset accessories, and in particular, relates to a holding case for installing handset add-on lens, a handset external lens connection structure and a handset installation case.
With the development of the society, more and more people began to use handsets, especially smartphones. Thus, handset manufacturers nowadays try their best to add functions that may attract users to handsets, for example, photographing function. However, as limited by the size and weight of a handset, the handset integrated with photographing function usually may only perform simple photographing, so users' demands of long distance photographing, optical zooming, wide angle photographing, or fill light cannot be satisfied. Therefore, users of handsets with photographing function expect the emerging of an external handset accessory that may expand the photographing function of the handset, so as to meet their demands for high quality photographing.
Holding cases in prior arts for installing handset add-on lens are usually mounted on the back of a handset by snap-fitting, and a connection structure is provided on the holding case to be detachably connected to a back add-on lens, thereby aligning the mounted back add-on lens with a back camera of the handset itself. The holding case in prior arts for installing handset add-on lens has the following disadvantages: (1) the holding case of prior art is mounted on the back of the handset by snap-fitting, so that only a back add-on lens may be mounted thereon, whereas a front add-on lens cannot be mounted at the same time; (2) the holding case is mounted on the entire back of the handset by snap-fitting, as a result, the holding case has large size and weight, which is not only inconvenient to carry around, but also inconvenient to mount and demount. Also, most of the holding cases on the market cannot be accurately aligned with the camera of the handset, and manual adjustment usually needs to be relied on, which is very inconvenient.
One prior art discloses a lens assembly for smartphone, comprising a handset shell for protecting a handset, a connection member, and a lens group, wherein the handset shell has a through hole on an outer side of a camera of the handset and corresponding to the camera, the lens group is connected to the through hole by the connection member and thus forms an optical cooperation with the camera. However, in the lens assembly for smartphone of the aforementioned patent literature, because the connection member protrudes out of the handset shell, the entire handset shell assembly has bulky and irregular shape, which has negative effect for carrying the handset around; if the connection member is demounted, it easily goes missing. Also, the connection between the lens group and the connection member is a threaded connection or a snap-fit connection, and this connection structure is inconvenient, time consuming and effort consuming to mount and demount.
Normal methods for increasing the quality of handset photographing or filming usually include adding a separate fill light or adding a separate external lens. For example, another prior art discloses a light filling device for self-photographing with a handset, comprising: a fill light, a mounting holder and a recharging cord, wherein, the fill light is selectively connected to the mounting holder or the recharging cord in a detachable manner; the bottom of the fill light is provided with an USB port for connecting to the mounting holder or the recharging cord. However, in the aforementioned patent literature, when the fill light is snap-fitted on the handset, due to limitation of the structure of the handset itself, the fill light may only be snap-fitted on the upper end of the handset, but such arrangement would block the front camera or the back camera thereof, and frequently moving the fill light would cause abrasion to the front camera, the back camera or the handset shell.
An objective of the present application is to overcome the defects in prior art related to undesirable connection structure of holding cases for installing handset add-on lens, which causes the handset shell to be bulky and causes the handset to be inconvenient to carry around, assemble and disassemble, by means of providing a holding case for installing handset add-on lens, a handset external lens connection structure and a handset installation case that have simple and compact structure and are easy to assemble and disassemble.

As shown in
The front add-on lens snapping opening 2 and the back add-on lens snapping opening 9 may or may not have the same structure. In this embodiment, as shown in
As shown in
At least one protruding first rib 102 is formed on the inner wall of the snapping opening 101.
At least one protruding second rib 104 is formed on the outer wall of the fitting head 103.
A protruding shoulder is provided on the outer wall of the fitting head 103 and disposed opposite the second rib 104, so as to form a snapping slot between the second rib 104 and the protruding shoulder, the first rib 102 is adapted for entering the snapping slot with the rotation of the snapping opening 101 after the fitting head 103 is inserted into the snapping opening 101, and the fitting between the first rib 102 and the snapping slot is changed from a clearance fitting into an interference fitting in the process of the first rib 102 entering the snapping slot.
In this embodiment, the first rib 102 on the snapping opening 101 is rotated into the snapping slot of the fitting head 103, and as the rotation angle increases, the fitting between the first rib 102 and the snapping slot is changed from a clearance fitting to an interference fitting, so as to achieve axial fastening and rotational fastening between the fitting head 103 and the snapping opening 101. Therefore, the connection fastener assembly of this embodiment not only has a simple structure, but also is fast and reliable to connect, wherein the connection between the first fastener A and the second fastener B may be realized by simply inserting the fitting head 103 into the snapping opening 101 and then rotating for less than half a circle.
Furthermore, as the second rib 104 and the protruding shoulder form the snapping slot, the snapping slot is a curved slot, and a surface of the first rib 102 facing the second rib 104 or facing the protruding shoulder is formed as a helical surface. This structure is easy to implement and convenient to operate, wherein, as the rotation angle increases, the fitting between the first rib 102 and the curved slot is gradually changed into an interference fitting.
A plurality of the first ribs 102 are disposed symmetrically and spaced apart in the circumferential direction, and a plurality of the second ribs 104 are correspondingly disposed in the circumferential direction. In one aspect, two first ribs 102 are symmetrically disposed, and two second ribs 104 are symmetrically disposed. Also, a circular flange 105 is formed on the fitting head 103 and disposed opposite the second ribs 104, the circular flange 105 forms the protruding shoulder and cooperates with the two second ribs 104 to form two snapping slots.
When there are two second ribs 104, in one aspect, a line connecting one end of the second rib 104 to a center of symmetry and another line connecting the other end of the second rib 104 to the center of symmetry intersect at an angle of 80°, accordingly, a line connecting one end of the first rib 102 to a center of symmetry and another line connecting the other end of the first rib 102 to the center of symmetry intersect at an angle of about 100°, and as a result, the first rib 102 and the second rib 104 has a large contacting area, which makes the connection more reliable. In design, in one aspect, a line connecting one end of the first rib 102 to a center of symmetry and another line connecting the other end of the first rib 102 to the center of symmetry intersect at an angle of 96°, so that a gap of 4° is reserved for the second rib, thereby avoiding the inevitable rounded corners left by cutting tools when machining the first rib 102 and the second rib 104.
As a variant of Embodiment 2, in this embodiment, the second rib 104 and the protruding shoulder form the snapping slot, a surface of the second rib 104 facing the protruding shoulder or a surface of the protruding shoulder facing the second rib 104 is formed as a helical surface, and the first rib 102 is a curved rib.
As an alternative embodiment, a protruding shoulder is provided on the inner wall of the snapping opening 101 and disposed opposite the first rib 102, so as to form a snapping slot between the first rib 102 and the protruding shoulder, the second rib 104 is adapted for entering the snapping slot with the rotation of the fitting head 103 after the fitting head 103 is inserted into the snapping opening 101, and the fitting between the second rib 104 and the snapping slot is changed from a clearance fitting to an interference fitting in the process of the second rib 104 entering the snapping slot. However, as the first rib 102 and the protruding shoulder have to be formed inside the snapping opening 101, it is relatively not easy to manufacture. Hence, the configuration of the above-mentioned Embodiment 2 is preferably implemented.
Furthermore, as the first rib 102 and the protruding shoulder form the snapping slot, the snapping slot is a curved slot, and a surface of the second rib 104 facing the first rib 102 or facing the protruding shoulder is formed as a helical surface.
As a variant of Embodiment 4, in this embodiment, the first rib 102 and the protruding shoulder form the snapping slot, a surface of the first rib 102 facing the protruding shoulder or a surface of the protruding shoulder facing the first rib 102 is formed as a helical surface, and the second rib 104 is a curved rib.
The operation process of the connection fastener assembly of this application is as follows:
When connecting the first fastener A with the second fastener B, the fitting head 103 of the second fastener B is inserted into the snapping opening 101 of the first fastener A so that each second rib 104 is inserted into a space between two neighboring first ribs 102, and then the first fastener A or the second fastener B is rotated so that the fitting between a back surface of the first rib 102 and a back surface of the second rib 104 changes from a clearance fitting to an interference fitting, thereby achieving reliable connection between the first fastener A and the second fastener B.
When detaching the connection between first fastener A and the second fastener B, it only requires to reversely rotate the first fastener A or the second fastener B so that the fitting between a back surface of the first rib 102 and a back surface of the second rib 104 changes from an interference fitting to a clearance fitting, and when each of the second ribs 104 is rotated to be disposed in the space between two neighboring first ribs 102, the fitting head 103 may then be pulled out from the snapping opening 101.
This embodiment provides an external lens connection structure for handset, which comprises the aforementioned connection fastener assembly, wherein, a handset protection case has the first fastener A, an external lens has the second fastener B, the snapping opening 101 is a through-hole aligned with and connected to a camera of the handset, an end of the external lens connecting to the handset protection case is formed with the fitting head 103. The connection fastener assembly is used for connection between the handset protection case and the external lens, and is convenient and fast to connect. Besides, because the snapping opening 101 is formed on the handset protection case while the fitting head 103 is formed on the external lens, when the handset protection case is not connected to the external lens, the portability of the handset would not be adversely affected by the existence of a fitting head upon the surface of the handset protection case. This kind of configuration is preferably implemented.
Of course, as an alternative, a handset protection case may have the second fastener B, an external lens may have the first fastener A, the handset protection case is formed with the fitting head 103, a through-hole at the center of the fitting head 103 is aligned with and connected to a camera of the handset, an end of the external lens connecting to the handset protection case is formed with the snapping opening 101. This kind of configuration is also convenient and fast to connect, but because the fitting head 103 would protrude from the handset protection case, the portability of the handset is adversely affected.
Wherein, as the fill light is fixedly connected on the handset installation case, instead of being directly connected to the handset, it would not abrade the handset shell, and because the fill light is connected on the third side wall 214, it would not obstruct a front camera or a back camera and also would not abrade the front camera or the back camera.
Specifically, in this embodiment, the connection structure 211 is a snap-fit connection structure. By using a compact snap-fit connection, a simple structure is achieved, which is convenient to assemble and disassemble, and after external accessories are connected thereon, the entire product has a good-looking appearance.
Besides, as shown in
In this embodiment, as the handset installation case is sleeved on the handset and has a relative large surface area, multiple connection structures 211 may be arranged on the handset installation case according to use requirements, so as to connect to external handset accessories for meeting multiple different functional requirements, i.e., not only a second connection structure 2112 for being fixedly connected to a back add-on lens may be provided at a position on the handset installation case corresponding to a back camera, but also a third connection structure 2113 for being fixedly connected to a front add-on lens may be provided at a position on the handset installation case corresponding to a front camera, so as to meet users' requirements for long distance photographing, optical zooming or wide angle photographing, and light compensation. Of course, users may also mount other handset accessories thereon according to their photographing requirements.
By providing resilient material 202 on two opposing inner side surfaces of the third side wall 214, hard contact and abrasion between the handset and the installation case is prevented, and the acting force between the two is distributed more uniformly, so that the mounting of the handset installation case is more stable.
As shown in
It should be noted that, according to actual requirements, the first connection structure 2111 for mounting the fill light may also be arranged on an outer side of either of the two opposing side surfaces of the third side wall 214.
Furthermore, the length of the first side wall 212 along the longitudinal direction of the handset is no longer than the distance from the edge of the handset to the display screen of the handset, so that normal use of the display screen is unaffected.
Specifically, the handset 220 has a control module with a function of controlling photograph-taking and/or video-taking, wherein the installation case 210 is sleeved on the handset 220; the fill light 230 is fixedly connected to the first connection structure 2111 of the installation case 210 and wirelessly connected to the control module such that turning on and turning off of the fill light 230 is controlled by the control module.
A front add-on lens 240 and a back add-on lens 250 are respectively fixedly connected to the connection structure 211 in such a manner that the back add-on lens 250 is fixedly connected to a second connection structure 2112, disposed on the second side wall 213 and corresponding to a back camera of the handset, for being fixedly connected to the back add-on lens; and the front add-on lens 240 is fixedly connected to a third connection structure 2113, disposed on the first side wall 212 and corresponding to a front camera of the handset, for being fixedly connected to the front add-on lens. Aside from the fill light 230 for light compensation of photograph-taking or video-taking, the front add-on lens 240 and the back add-on lens 250 are provided to further meet users' requirements for long distance photographing, optical zooming or wide angle photographing.
The fill light 230, the front add-on lens 240 and the back add-on lens 250 respectively have a snap-fit structure for fitting the connection structure.
As an alternative, the connection structure 211 may be implemented by a threaded connection structure instead.
Apparently, the aforementioned embodiments are merely examples illustrated for clearly describing the present application, rather than limiting the implementation ways thereof. For a person skilled in the art, various changes and modifications in other different forms may be made on the basis of the aforementioned description. It is unnecessary and impossible to exhaustively list all the implementation ways herein. However, any obvious changes or modifications derived from the aforementioned description are intended to be embraced within the protection scope of the present application.
